Sum Up Here’s what we can learn from Nicholas: Hang out with the people you want to be: Behaviors spread like a virus. Make sure it’s one you want to be infected with. Make more friends. Time spent making friends has a higher happiness ROI than time spent making money. Introduce friends to friends. Friends becoming happy increases your chance of happiness by 45%. Keeping the network happy protects you against unhappiness. Other research Nicholas did turned up something truly heartwarming: friends are family. Quite literally.
Doing everything on your own can take you only so far. To go further you need supportive people.
